How much heat energy was lost by the liquid ethanol?

How much heat energy was gained by the solid ethanol "cube"

What is the heat of fusion of ethanol per gram?

3. A student performed an experiment similar to the one you did in Part B. except used liquid and frozen
ethanol instead of water. The goal of the experiment was to determine the heat of fusion of ethanol.
The student measured the following data and the known value of the specific heat of liquid ethanol is
0.502 In this experiment, the liquid ethanol transfers heat energy to the solid ethanol to melt it
Experimental Data
mass solid ethanol
25.20 g
mass liquid ethanol in calorimeter
100.00 g
initial temperature of liquid ethanol in calorimeter
-100.0 °C
final temperature of liquid ethanol in calorimeter
initial temperature of solid ethanol
-112.5 °C
-114.0 °C
Use the table below to organize the information for the liquid ethanol.
Liquid Ethanol
